No-trim wall border

If you’re building a fence or a retaining wall, set a course of protruding stones in the soil beneath it. That way, your mower can cut all the grass – no hand trimming needed. The stones should protrude about 10cm from the wall and stand at least 3cm above the soil so grass doesn’t creep over them. You’ll still have to pull out grass from between the stones occasionally.
Use accent lights

Using even just a small accent light can work wonders for the dark corners around the yard. Not only will it create even more beauty, but it can also help keep away potential intruders who seek out dark places to stay unnoticed.
Add a water feature

A water feature, such as this soothing DIY fountain, provides the soothing sight and sound of running water people love. Another bonus – since birds love moving water, there’s a chance you’ll attract some of these outdoor friends.
